Perhaps you should try some spelling variations:
tham thuc » nham thuc, pham thuc, tam thuc
cham tuc » nham thuc, pham thuc, cham soc
te sach » toc sach
nang xa » nang x, lang xa, nang ma
hieu ve » hieu va, hieu van
va danh » va dinh, va dan, va hanh
danh vi » hanh vi, dinh vi, danh di
sach 2 » sach y
2 nang » v nang
vi cua » vai cua, di cua

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: te sach 2 nang xa hoi. hieu ve ((cham tuc) OR (tham thuc)) va danh vi cua vat~.
• Adding a wildcard symbol may retrieve word variants: te sach 2 nang xa hoi. hieu ve ((cham tuc) or (tham thuc)) va danh vi cua vat*.
